"We have made the official call and will start on Monday, July 31 at 7:00 a.m. local time," said Mike Parsons, WSL Big Wave Tour Commissioner. "We have been closely tracking the conditions and have determined that Monday will be the peak of swell and when we will see the biggest surf. We have ruled out Sunday as we are seeing an increase in size for Monday in the 20-to-25 foot range. We are excited for a great event."

This will be the second BWT event at Mainland Mexico's Puerto Escondido, which is home to one of the most monstrous and demanding waves on earth. With a volatile sandbar bottom, the world-renowned beachbreak requires technical mastery, extreme physical endurance, and boundless courage from all who accept the challenge.

Surfline, Official Forecasters for the 2017 WSL BWT season are calling for:

Based on the latest satellite and buoy data, we expect to see a building trend in surf through the morning on Monday, with a peak in swell around mid day for Puerto Escondido. For the early morning hours we'll look for the better sets to be in the 15-20' range on the face, with the very largest waves pushing up to 25' on the face. As the swell fills in through the morning and peaks into the early afternoon we expect to see larger 18-25' faces on the better sets, with max sets of the day up to 28' faces. Offshore wind in the early morning should give way to a light+ seabreeze from the SW over the later morning and afternoon.
